Molecular Identification of Zantedeschia Culture with Determination of Its Morphometric and Metabolic Activities for Mediterranean Acclimatization

Calla lily (Zantedeschia albomaculata (Hook.) Baill.) is an herbaceous or semi-evergreen perennial grown from rhizomes. It is commonly named “Spotted Arum”. Ribosomal RNAs (rRNAs) are found in all known organisms and are known for being functionally equivalent in all of them. A completely new in vitro culture protocol was applied to Z. albomaculata with two hormones, 6-Benzylaminopurine (BAP) and kinetin, to obtain full growth and multiplication. Due to their highly conserved sequences, the analysis of small-subunit rRNAs (16S–18S rRNAs) can provide precise statistical evaluation of a wide variety of phylogenetic connections. As a result, the plant’s 18S rRNA gene allowed for identification and partial sequencing. Also, the traditional floral method and the novel application technique for identification were applied to Z. albomaculata. In this paper we systemically describe the structural strategies of the plant’s adaptation to the surroundings at the morphological, physiological, and anatomical scale. Most the essential oils and fatty acids found in Z. albomaculata are omega fatty acids, octadecenoic acid, linoleic acid, and palmitic acid. All these fatty acids have industrial, medicinal, and pharmaceutical applications. The significant findings are the spadix sheathing leaves, and the precipitation of raphides calcium oxalate. The mitotic index showing the division activity was recorded, and it was 17.4%. The antimicrobial activity of Z. albomaculata ethanol extract was performed via the well diffusion method. This extract has shown high activity against Escherichia coli and Pseudomonas aeruginosa, compared to its lower activity against Bacillus cereus. By defining these characteristics and in vitro culture conditions, we will be able to acclimatize the plant in greenhouses, and then transfer it to the open field. The findings of this work identified the general characteristics of Zantedeschia albomaculata as an ornamental and medicinal plant in order to acclimatize this plant for cultivation in the Mediterranean climate.

Morphological Description
Variable morphological measurements were recorded for the description of Zantedeschia plant. The data were estimated after 4 weeks of in vitro culture on MS media and recorded in Table 1 and Figure 1. The stem was mosaic with colored dots, and the leaf is curved and bending outward and of the spathe-leaf type. The leaves are arrow-shaped, semi-erect, broad, wavy, and covered with sheath. Some of the essential primary and secondary metabolites were estimated for Zantedeschia albomaculata after 4 weeks of in vitro culture. These metabolites included chlorophyll pigmentation (chlorophyll A and B), carotenoids, xanthophyll, total protein, phenolic compounds, and flavonoids (Table 2). These metabolites have essential roles in plant activity and viability. The chlorophyll index illustrates the activity of photosynthetic rate, and it was observed that the chlorophyll index for the fresh green leaves was 3.1. However, these leaves wilt rapidly and are transferred into yellow leaves within days if the incubation conditions are not suitable. The chlorophyll index for these yellow leaves decreased more rapidly and was recorded as 1.1.

So, the most essential oils and fatty acids are omega fatty acids, Octadecenoic acid, linoleic acid, and palmitic acid. Omega-6 fatty acids are a type of polyunsaturated fat that are good for the heart and appear to protect against heart disease. Omega-7 fatty acids are a class of unsaturated fatty acids and widely used in cosmetics due to their moisturizing properties. Octadecenoic acid is saturated fatty acid and used in hardening soaps, softening plastics, and in making cosmetics, candles, and plastics. Linoleic acid is polyunsaturated fatty acid and used as emollient or moisturizer for skin, nails, and hair. Palmitic acid is a saturated long-chain fatty acid used to produce cosmetics and soaps.

Some of the fractions are illustrated in Figure 5. These compounds and fractions were identified in the provided report sheet based on the data obtained.

Anatomical Studies
The variable Zantedeschia organs have varied and qualitatively described anatomical features in the stem, root, and leaf ( Figure 6). The stem is hollow with elongated epidermal cells and oil precipitation in cells. The root is very tiny and covered with unicellular hairs on surface. The leaves have obvious chlorophyll pigmentation aggregates as well as Ca. oxalate precipitation (raphides and solitary). The stomata in leaves are of paracytic type with two subsidiary cells parallel to the guard cells. The essential compounds obtained from LC-MS have antibiotic, antioxidant, and anticancer activities. Vanillic acid is a tannin and exhibits diverse bioactivity against cancer, diabetes, obesity, neurodegenerative, cardiovascular, and hepatic diseases by inhibition of the associated molecular pathways. Caffeoylquinic acid (CQA) is one of the phenylpropanoids which exhibit various bioactivities such as antioxidant, antibacterial, anticancer, antihistaminic. Chlorogenic Acid is a polyphenol and the ester of caffeic acid and quinic acid that has potential antioxidant activity. Roseoside is known as rose oxide, which is a class of monoterpenes used for high-value perfume and cosmetics.

Antimicrobial Activity
The ethanolic extracts of the Zantedeschia plant possess antimicrobial activity, as it could inhibit the growth of tested food pathogens and spoilage microorganisms. This inhibition is achieved via the clear zones ( Figure 8). The extract was more resistant to E. coli followed by P. aeruginosa, and less resistant to B. cereus.

Discussion
This study introduced a whole protocol for the in vitro culture with a complete definition for the variable morphological, physiological, anatomical, antimicrobial, and molecular behavior of Z. albomoculata. In this study, the in vitro culture of Z. albomoculata was supplemented with 3 BAP and 0.5 Kin. The growth regulators used in the first experiment in the multiplication stage are cytokinins. This is closely related to Ruiz et al. [7] who initiated Zantedeschia aethiopica culture and supplemented the media with 1 mg dm-3 BAP; and Kulpa [15] who supplemented the MS medium with 1.0 BAP and 2.5 BAP. The effectiveness of BAP for the multiplication of plants of the family Aracaeae was confirmed by [16]. Chang et al. [17] modified a method for the micropropagation of Zantedeschia albomaculata from shoot tip culture with the application of several phytohormones (TDZ, BA, Kinetin, 2iP, IAA, NAA, and IBA). However, in this study only two growth hormones (BAP and kinetin) were used to achieve more reproducible results.

Morphology describes a plant's external appearance. It is considered to be the most crucial foundation for taxonomic description. Additionally, morphology is seen as an antiquated method but is nevertheless a crucial foundation for dealing with taxonomic difficulties. The most essential indicator for identifying plants visually is the morphological structure, so studying morphology is thought to be an important approach to determine the easiest technique for researchers to clarify the genus. Consequently, the identification and classification of the diversity of plants should be considerably simpler, particularly when naming the species, family, or kingdom [19][20][21][22].
For more or less a century and a half, the features of plant internal structure have contributed to plant systematics. Additionally, phylogenetic relationships have been identified and determined using the anatomical structure of plants. Light microscopes, simple techniques, and electron microscopes are used to observe the anatomical properties. The anatomy of organs, which includes leaf, stem, root, and flower, is one of the most fundamental and taxonomic components of anatomical characteristics. Additionally, the anatomical traits can support the elaboration of a genetic relationship or phylogenetics [23].
Similar to other Araceae plants, Zantedeschia albomoculata has calcium oxalate crystals that are insoluble. When consumed, these crystals hurt, make swallowing challenging, temporarily make one hoarse, and induce edema. This is due to the fact that these crystals puncture the delicate tissues in the throat, gums, and tongue. Also typical is GI tract irritation. The mucilage of the cells containing raphides needles is a polysaccharide from a histochemical perspective since it colors red when subjected to Schiff's reagent. In general, the mucilage idioblasts connected to the vascular bundles and the epidermis have been thought of as water storage cells and are therefore important for adaptation in hotter environments [24]. The number of stomata on both leaf surfaces, the lack of any compartmentalization, the fine structure of the spongy parenchyma, including the arrangement of the cells and the distribution of chloroplasts along the cell walls facing intercellular spaces, may all reduce the amount of CO 2 diffusion resistance [25]. It has been demonstrated that plants are very adaptable to variations in spectral quality in terms of their physiology, morphology, and anatomical structure [17,26].
Numerous studies have looked at the effectiveness of plant extracts and their antimicrobial properties in preventing the growth of bacteria that cause food poisoning and spoiling. Some researchers have hypothesized that terpenoid, alkaloid, and phenolic compounds found in plant extracts act as antimicrobial agents by disrupting the microbial cell membrane and causing a flux of protons to move outward, causing cell death, or by impairing enzymes required for the biosynthesis of amino acids [27][28][29][30][31][32]. Plant extracts are regarded as readily biodegradable, nutritionally safe sources of antibacterial agents [33,34].
Many studies have proved that Zantedeschia species have chromosome number 2n = 32 [19][20][21]. However, no previous work has estimated the mitotic index in Zantedeschia to illustrate the activity and viability of cell division.
Phytochemical and pharmacological studies have shown that compounds found in Z. aethiopica extracts have antifungal, antibacterial, and antioxidant properties. Both Nielsen et al. [35] and Pratush et al. [36] evaluated the antibacterial activity of methanol and ethanol extracts of the leaf and stem of Z. aethiopica, which exhibited activity against different bacterial strains.

Plant Material
The explant of Zantedeschia was introduced into "Vitro Plant Labs" (plant tissue culture specialist)-Egypt, where the practical tissue culture work was performed.

In Vitro Culture Conditions and Multiplication
The protocol for the establishment of the Z. albomaculata culture was as follows: "segments were sterilized and cultured on free MS media for one month. The explants were defoliated and washed carefully in fluid tap water to eliminate all the stacked dust/soil practices. Tailed with surface sterilization of the explants were using 20% Clorox + 0.1% HgCl 2 for 20 minutes and washed 4 to 5 times with double distilled sterile water. Excising and procedure of culture for explants stem nodal was performed under sterilized condition. MS basal medium contains required nutrients of macro-and micro-elements for the in vitro cultured plants as described by Murashige and Skoog [37]. The medium was allocated into incubation jars where each jar contained 50 mL. Stem nodal cultures were incubated at 25 ± 2 • C and satisfactory fluorescent light of 3000 Lux for 16-hour photoperiod provided by cool, white, fluorescent lamps".
The shoots formed as a result of the establishment process were excised and transferred into a new multiplication MS medium supplemented with 3 mg/L of BAP + 0.5 mg/L Kin in order to obtain micro-shoots required for the multiplication experiment [15]. The multiplication process was repeated as sub-culture for three times, in order to record the study data.

Plant Identification
The identification of Z. albomaculata was performed via three methods: floral identification for the different vegetative parts, digital identification using the mobile application LeafSnap, and finally molecular identification using 18srRNA.

Floral Identification
The Boulos [38], and Kadereit and Jeffrey's [39] protocol was followed for the morphological identification and description of the cultured Zantedeschia samples.

Digital Identification
Researchers from the Smithsonian Institution, the University of Maryland, and Columbia University are the creators of the LeafSnap series of computerized field guides. Through the use of free mobile apps, tree species can be determined from images of their leaves by using visual recognition software [40] (http://leafsnap.com/dataset/, accessed on 12 August 2022). This application is used to identify Zantedeschia sample via leaf.

Molecular Identification DNA Extraction
The whole genomic DNA was isolated according to the method of Edward et al. [41], as follows: "500 mL of CTAB buffer (2% CTAB, 2% polyvinylpyrrolidone, 1.4 M NaCl, 20 mM EDTA pH 8.0, 100 mM Tris HCl pH 8.0) was added to 0.5 g of specimen's leaflet. The sample was heated in a water bath at 65 • C for approximately 1 h. One volume of chloroform-isoamyl alcohol (24:1) was added to the sample and mixed by inversion for 10 min and then centrifuged for 30 min at 13,200 g. The aqueous phase was collected into a clean microcentrifuge tube and the rest was discarded. Two volumes of absolute ethanol were added with 0.1 volumes (approximately 50 mL) of sodium acetate 3M pH 5.2 and mixed gently. The sample was left for at least 20 min at −20 • C and then centrifuged for 30 min at 13,200× g. The supernatant was discarded, and the pellet was rinsed in 70% ethanol and dried at room temperature. The pellet was dissolved in 50 µL of TE buffer (1 mM Tris HCl pH 8.0, 0.1 mM EDTA pH 8.0)." 18S rRNA PCR Amplification PCR amplifications of Zantedeschia 18S rRNA gene, from the purified genomic DNA, were carried out using the primer sets, EUK1.f, 5 -AGCGGAGGAAAAGAAACTA -'3; and EUK2.r, 5 -TACTAGAAGGTTCGATTAGTC -'3. PCR reaction mixture, 25 µL, contained 12.5 µL of master mix, 1 µL of each primer, and 50 ng DNA template. PCR was performed with an initial denaturation step of 5 min at 95 • C. The PCR reaction continued with 35 cycles of 30 sec at 94 • C, 30 sec at the annealing temperature of 54 • C, and 1 min extension at 72 • C. The final extension was at 72 • C for 10 min for one cycle. The purified 18S rRNA gene amplicons were analyzed directly by sequencing, using an ABI 3730xl DNA sequencer by using forward and reverse sequences, and combining the Traditional Sanger with the new 454 technology (GATC Company, Germany) [42].

Morphological Description
The following eight morphological biometric parameters were measured for all these treatments: "plantlet fresh weight, shoot length, branch number, root number, root length, leaf length, leaves number and leaf weight". Seven to ten replicates for each parameter were measured for accurate mean results.

Chlorophyll Index
Chlorophyll index is applied to calculate the total amount of chlorophyll in plant leaves. It was measured using OPTI-SCIENCES (CCM-200 plus) to indicate the photosynthesis rate in Zantedeschia sp.

Pigmentation
Chlorophyll a, b, and carotenoids were measured in the plantlets' fresh leaves according to the method of Metzenr et al. [43]. "In 5 mL of 85% acetone, a known weight of fresh leaves (0.5 g) was homogenized. The pigment-containing supernatant was made up to a definite volume (10 mL) with 85% acetone after centrifugation. At three wavelengths (452, 645 and 664 nm), the extract was compared to a blank of pure 85% aqueous acetone using a colorimeter. The concentration of chlorophyll a, b and carotenoids were calculated as µg/g leaf fresh weight using the following equations": Then, the fractions were calculated as mg/g fresh weight: Conc. = Fraction * Dilution 1000 Equations for the calculation of concentrations of lutein (xanthophyll pigmentation) in Zantedeschia leaves were obtained according to the method of Bulda et al. [44], using specific absorption coefficients of lutein at 480 and 495 nm, as follows: where A is absorption of the solution at 480 and 495 nm, C let is the concentration of lutein as a type of xanthophyll pigmentation; concentration of lutein (mg/L).

Total Proteins
The total protein was extracted according to the method of Bradford [46] and some modification by Hussien [45], as follows: "Weight 0.5 g of leaves was weighted and grind well with 0.5 mL of [2x] Bradford reagent. Then vortex 10 min and centrifuge for 15 min at 24,104 g at 4 • C. The supernatant contained the total protein content of plant species". Finally, the protein concentration was estimated according to the method of Bradford [46], as follows: "0.1 mL of supernatant was pipette into a test tube and 5 mL of protein reagent was added, mixed and measured by spectrophotometer at wavelength 595 nm. The concentration of protein was determined from the protein standard curve (using bovine serum albumin)." The concentration was calculated according to the following equation: where X was the protein concentration (mg/g), and Y the absorbance (nm).

Total Phenolic Compounds
Air-dry powdered Zantedeschia (1 g) was extracted by stirring 30 ml methanol (80%) at room temperature until the extraction solvent became colorless. Total phenolic contents were determined according to the method described by Wang et al. [47], using Folin-Ciocalteu reagent and gallic acid as a standard. Briefly, 0.5 ml of filtered extract was added to a test tube containing 2.5 mL Folin-Ciocalteu's reagent (diluted with ethanol 1:1), 2 mL of Na 2 CO 3 (7.5%) and mixed well. After 15 min incubation at room temperature, the absorbance of mixtures was recorded spectrophotometrically at 765 nm using a Jenway 6405 UV-Vis spectrophotometer. The total phenolic content was calculated from a calibration curve of gallic acid standard solutions and expressed as mg gallic acid equivalent (GAE) per gram of extract (mg GAE/g dry weight of extract).

Total Flavonoids
The total flavonoids content of Zantedeschia extract was determined using aluminum chloride colorimetric assay [48]. An amount of 0.5 ml of the extract was added to 150 µL of 5% NaNO 3 and allowed to stand for 6 minutes. Then, 150 µL of 10% AlCl 3 solution was added and allowed to stand for 6 min, after which 200 µl solution of 1 M NaOH was added, and then the mixture was completed to 5 mL with methanol and mixed well. After incubation for 15 min, the absorbance was measured spectrophotometrically against a blank at 510 nm. The total flavonoids content was expressed in milligrams of quercetin equivalents (QE) per gram extract (mg QE/g). The standard curve of quercetin was used for the calculation of total flavonoids. Both the total phenolic compounds and total flavonoids content were calculated according to the following equation: The total oil of Zantedeschia was obtained by the hydro-distillation technique using Clevenger's apparatus. One hundred grams from plant materials were placed in a two-liters round bottom flask and distilled water was added and mixed thoroughly. The contents of the flask were boiled gently for four hours until the volatile oil was distilled. The crude volatile oil of the plant was transferred by means of a pipette into a separate brown glass bottle. Anhydrous sodium sulphate was added and agitated gently to absorb the water, and the clear oil was decanted into the brown glass bottle and kept in the refrigerator until needed for analysis [44]. After that, the oil was analyzed using GC-MS technique.
Mass spectra were recorded using a Shimadzu GCMS-QP2010 (Tokyo, Japan) equipped with Rtx-5MS fused bonded column (30 m × 0.25 mm × 0.25 µm film thickness) (Restek, Bellefonte, PA, USA) equipped with a split-spitless injector. The initial column temperature was kept at 45 • C for 2 min (isothermal) and programmed to 300 • C at a rate of 5 • C/min, and kept constant at 300 • C for 5 min (isothermal). The injector temperature was 250 • C. The helium carrier gas flow rate was 1.41 mL/min. All the mass spectra were recorded applying the following condition: (equipment current) filament emission current, 60 mA; ionization voltage, 70 eV; ion source, 200 • C. Diluted samples (1% v/v) were injected with split mode (split ratio 1:15) [49].

Preparation of Zantedeschia Methanol Extract and LC-MS
About 10 g of Zantedeschia were transferred into a screw-capped extraction tube and extracted with 10 mL of 70% aqueous methanol at 75 • C for 60 min. After centrifuging at 4000 rpm for 5 min, 3 mL of supernatant was transferred to a 5 mL vial. The solution was filtrated through a syringe filter with a 0.2 µm membrane for the quantification of apigenin and apigenin 7-glucoside in the plant material by LC-MS.

Anatomical Description
Traditional botanical microtome technique is used to make thin cuts for examination under a microscope. A blade is used to cut the leaves, stem, and root to examine the variable anatomical features of Zantedeschia species used in this study. The materials are hardened by replacing the water in the materials with paraffin so that they can be cut. The steps required in using paraffin to make a permanent slide [50].
The protocol was as follows: Cut a fresh sample and put it in an FAA fixative for 24-48 h, then wash by distilled water and put in different ethanol concentrations (70% and 80%) for 48 h, then transfer sample to 95% ethanol for 2 h, and absolute ethanol for 2 h. After that, transfer the sample to serial concentrations of absolute ethanol and chloroform (3:1, 2:1, 1:1, 1:2 and 1:3) for 2 h for each concentration, then transfer the sample to absolute chloroform for 12 h. Add wax granules to samples three times for three days. (Taste the liquid to be sure that wax replaces chloroform). Discard the wax, and then add a new clean molten wax to the sample to wash it several times. Prepare an L-letter and a glass rod painted with glycerin, pour the molten wax inside the L-letter (remove air bubbles by moving forceps in the molten wax), and then put the sample inside the wax. Pass air from mouth on glass plate surface to dry it, and then put it in water slowly to remove air bubbles.

Cytological Studies
The geminated beans' roots were used for chromosomal examination for the calculation of mitotic indices to estimate the chromosomal activities of beans seedlings under different treatments of other plants. Feulgen squash technique was used to stain the chromosomes. The procedure was performed according to the method of Boscaiu et al. [51], as follows: The root tips were fixed in glacial acetic acid: ethanol (1:3) after a pre-treatment of 2 h in 0.2% colchicine. For staining, the Feulgen standard method was used. After a 5-10 min wash in distilled water, the root tips were hydrolyzed for 30 min in 5 M HCl at room temperature, then transferred to distilled water and stained for 30 min to 1h in leuco-basic fuchsine reagent. Finally, squash preparations were carried out in a drop of 45% glacial acetic acid and examined under the microscope.
The mitotic index can be calculated from a slide with electric microscopy. It is the number of cells containing visible chromosomes divided by the total number of cells in the field of view. Nearly 1000 cells were examined for each different bulb of the species to determine the rate of mitotic division (mitotic index), phase index, mitotic stage index, and to determine abnormalities in chromosomes. Calculations were performed according to the method in Mishra, et al. [52] as follows: M.I = Number o f dividing cells total number o f dividng and nondividing cells * 100

Antimicrobial Activity of Zantedeschia Extract
The ethanol extract of the two fruits' peels was tested against Gram-positive bacterial strain Bacillus cereus, and Gram-negative bacterial strains Escherichia coli and Pseudomonas aeruginosa. This assay was applied using the agar plate diffusion method according to Kavanagh [53]. One ml of the standardized bacterial stock suspension (108-109 CFU/mL) was mixed with 100 ml of molten sterile nutrient agar which was maintained at 45 • C.
Twenty ml aliquots of the inoculated media were distributed into sterile Petri-dish plates (9 cm). The bacterial cultures were maintained on nutrient agar and 100 µL of plants ethanol extract was inoculated in wells, then incubated at 37 • C overnight. The control bioassay was applied by inoculating only ethanol in wells.

Statistical Analysis
The gel electrophoresis images were analyzed as 1 (band present) and 0 (band absent). These computations were carried out using Bio-Rad Quantity one (4.6.2) [54]. Zantedeschia was aligned with NCBI data to estimate the phylogenetic relationship among these species. In SPSS 21, the data was subjected to an analysis of variance test. Standard deviations, and mean averages were calculated.

Conclusions
The current study manipulated the floral, digital, molecular, morphological, physiological, cytological, and anatomical identification structures of Zantedeschia albomoculata, specifically in the root, stem, and leaf. Descriptive qualitative and quantitative approaches were applied to ensure the enough identification for the plant, especially given that it has few previous records. Morphologically, the leaves are distinctive with the formation of a sheath around the stem forming a spadix. The most characteristic anatomical feature is the formation of raphides and solitary calcium oxalate as a defense mechanism for this plant. The most significant physiological phenomenon is the rapid yellowing and wilting of leaves and a remarkable decrease in chlorophyll content. The essential fatty acids found in these species have multiple applications in many fields. The ethanolic extract has shown antimicrobial activity against some gram-negative and gram-positive bacteria. To sum up, Zantedeschia albomoculata is an essential ornamental plant, and it needed to be identified as explained in this work. All these defined parameters enable the plant to be acclimatized and cultivated in the Mediterranean climatic conditions.
